Abstract

A method of assembling a fan wheel (62) includes forming a first wheel portion (100) including a first plurality of impeller blades (108) and a first connector (130), forming a second wheel portion (102) including a second plurality of impeller blades (144) and a second connector (132), affixing an end (118) of each of the first plurality of impeller blades to a first surface (142) of a support ring (104) such that the first connector is affixed to the second connector, and affixing an end (120) of each of the second plurality of impeller blades to a second surface (146) of the support ring.
